inline functions

[Kövesdi György]

Thanks, I already got the answer from John <eljay@adobe.com>.

It can be useful for ohers, so here are the details:
The compiler has some limits inside to make functions inline. My source cannot 
be published here because of its complexity, and that was the problem: the 
mentioned class was inherited from other classes, using more inline 
functions. The option "-Winline" gives more information in such cases.
The essence is the option "max-inline-insns-single", which is described in 
details in "man gcc". The inlining limits can be changed this way.
The source code is mentioned in my previous mail "C++ in embedded systems"

Thanks again,
K. Gy.
